/**
 * Smarty {html_table} function plugin
 *
 * Type:     function<br>
 * Name:     html_table<br>
 * Date:     Feb 17, 2003<br>
 * Purpose:  make an html table from an array of data<br>
 * Input:<br>
 *         - loop = array to loop through
 *         - cols = number of columns, comma separated list of column names
 *                  or array of column names
 *         - rows = number of rows
 *         - table_attr = table attributes
 *         - th_attr = table heading attributes (arrays are cycled)
 *         - tr_attr = table row attributes (arrays are cycled)
 *         - td_attr = table cell attributes (arrays are cycled)
 *         - trailpad = value to pad trailing cells with
 *         - caption = text for caption element
 *         - vdir = vertical direction (default: "down", means top-to-bottom)
 *         - hdir = horizontal direction (default: "right", means left-to-right)
 *         - inner = inner loop (default "cols": print $loop line by line,
 *                   $loop will be printed column by column otherwise)
 *
 *
 * Examples:
 * <pre>
 * {table loop=$data}
 * {table loop=$data cols=4 tr_attr='"bgcolor=red"'}
 * {table loop=$data cols="first,second,third" tr_attr=$colors}
 * </pre>
